I’m not an expert but I remembered this article from a decade ago which you might find interesting. The reporter, Robb Walsh, wrote the Texas BBQ Legends book.
Clarence Pierson was the first of the craft bbq movement in Houston. Unfortunately health issues forced him to retire.
The article uses ‘cellophane’ and ‘plastic wrap’ interchangeably it seems, but cellophane is not Saran Wrap (I looked it up).
However, this is for holding the meat as I understand it, not getting past the stall.
